v SHREDDER KNIFE FOR ENSILAGE CUTTER/S,

Specification of Letters Patent.

Application filed June 10, 1916. Serial No. 102,886.

To all whom it may concern.-

Be it known that I. THonAs E. \VEBB, a citizen of the United States.residing at Shortsville, in the county of Ontario and State of New York,have invented certain new and useful Improvements in Shredder Knives forEnsilage Cutters, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to certain new and. useful improvements inshredder knives adapted to be used in connection with ensilage cuttersin which a cutting wheel is provided upon one face with a series ofknife supports on which are adapted to be arranged tangentiallyshredderknives forshredding material fed to said knives.

Another object of my invention is to pro vide a shredder knife in whichthe beveled cutting edge thereof is serrated, the portion between theteeth formed by said Serra tion being formed on curved lines in order toprevent the material from .wedging between th teeth of said knives, andto increase the strength so as to prevent the teeth from being brokenoff when the knives are in operation.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claim.

I11 the drawings,

Figure l is a plan view of a shredder knife having a straight andoblique cutting edge.

Figure 2 is a section taken on the line 3-3 of Fig. 1.

Like numerals of reference refer to like parts in the several .tignresofthc drawing.

My improved shredder knife is adapted to be used in connection withknife supports for cutting wheels as shown in the application of F. J.Bullock filed April 5, 1916. N 0. 89,145 and patented Aug. 7, 1917,1,236,259 in which a series of shredding knives are adapted to bearranged tangentially in one face of the cutting wheel. so that thematerial fed to said shredder knives will be thoroughly shredded.

which. the bolts tion of said cutting edge bein In the form of ashredder knife as shown in Figs. 1 having the usual bolt openings 2through are adapted to pass for mounting the same on the cutting wheel.One edge of the knife is formed with a straight beveled portion 8terminating in an oblique beveled portion 4, the beveled edgesthusformed being notched or serrated to form teeth 5, the bottom of thenotches being formed of curved lines as shown at 6 so as to provide aknife with aseries of teeth emerging into one another by curved lineswhich increases the strength of the knife thus formed and prevents theteeth from becoming choked when the cutting knife is in operation. Byconstructing a knife with an end portion arranged at an angle to theother portion when the knife is in position on a rotary cutting wheel.the angle portion which travels in a small circle cuts and shreds thefodder thoroughly.

From the foregoing description it will be seen that I have provided ashredder knife to be used in connection with an ensilage cutteremploying a rotary cutter wheel in the form of a disk upon one face ofwhich is adapted to be tangentially arranged a series of shredder kniveswhich are adjusted at the proper angle so that material fed to the sameis thoroughly shredded.

I claim:

A shredder knife for rotary ensilage cutters comprising aflatsubstantially oblong body having a beveled cutting edge on one edge,said beveled edge being serrated to form a series of Spaced teeth, thenotches between the teeth terminating short of the bevel thereof. theportion between the teeth being formed on curved lines, the inner porarra nge d at an angle to the other portion thereof.

In testimony whereof I hereunto allix my signature in the presence oftwo witnesses.
